So, I followed the instructions to add Sega CD to the front end, but every time I choose a game it gives me a "File Too Large, May Not Be A Genesis/32x Game" error. Seems that the front end is trying to boot it into Genesis mode instead of Sega CD. Any ideas on how to fix this? I copied and pasted the config file straight from the post.

I get the same thing running Lunar 2. Personally I have the bin and cue in a zip file, which I believe is the problem. I haven’t tried unzipping them yet.

I think the Dreamcade gets into the zip file, but then tries to run the bin through Fusion instead of the cue.

To play any Sega CD roms, you must unzip in order for Fusion to play correctly. If you go to C:\menu\users\_da\games and open up PikoGames_PSX. That's how I write for my Sega CD roms. I have a 1TB drive in the HDD bay. I assign it H: letter. So I will create a game folder put the cue/bin, iso directly there. With the XML, its being told where the file cue file is, name of the game to appear in the game menu selection, and what " ".png to use for art, still, etc....

For example, this is how I have mine

H:\roms\segacd\mortal kombat

As you can see, I created segacd folder inside roms folder. then created a new folder for the game I wish to put inside, which in this case mortal kombat. So inside mortal kombat folder is where I have my cue / img and other files that are with mortal kombat

And now in my c drive
C:\menu\users\_da\games I have a XML file called Sega CD games
